Sophie van Oppenraaij went on a work visit to the International Congress of Nutrition of IUNS: Sustainable Food for Global Health, Paris, France, from August 24-29, 2025.
I attended the 23rd International Congress of Nutrition (IUNS-ICN 2025) from 24–29 August, themed Sustainable Food for Global Health. My goals were to learn about the latest developments in sustainable nutrition, dietary protein, and applications of plant-based diets for ageing and muscle health.
I was selected to present my study, Perspectives of adults aged 55+ on plant-based diets rich in protein, which was published the same week (https://pubmed.ncbi.nlm.nih.gov/40866478/). I felt both excitement and nerves before the presentation, but once on stage I genuinely enjoyed it. One tough question reminded me of the importance of preparing for all types of questions. While there is always room for improvement, I am pleased with the talk.
One session particularly stayed with me: a speaker argued that a shift towards more plant-based diets is economically unfeasible, noting that animal-source food intake typically rises with income. Because my PhD focuses on the protein transition toward more plant-based eating in the Netherlands (a high-income country), this perspective was both challenging and useful. It highlighted the importance of considering economics, policy, and behaviour alongside health outcomes if we want recommendations to translate into practice.
I left with relevant references for manuscripts in progress, a broader network, and valuable memories with colleagues. Overall, the congress was productive and motivating, and I returned with new energy for my PhD!
